The battle to take the Brighton Pavilion constituency will be one of the most closely-watched in this year's general election - and we want your to help everyone watch it even more closely.

Green Party candidate Caroline Lucas is hoping she will make history by winning her party's first ever Parliamentary seat.

But her opponents, Labour's Nancy Platts and the Conservative's Charlotte Vere, have other ideas.

We've launched an online map where you can log where you've seen the three main candidates - and if you spoke to them, what they said.

We've started it off by mapping the candidates' canvassing tweets, and the candidates themselves have contributed too - but we're more interested in your reports of what they said on the doorstep.

Please only include sightings of the candidates themselves, and no earlier than January 1, 2010.

To add a marker, click here and follow the instructions above the map.

Alternatively, email jo.wadsworth@theargus.co.uk and we'll add the marker for you.
